My invention relates to certain improvements in end Jtrames of locomotives.

The object of my invention is to make an integral casting containing a cylinder saddle,

center pin or guide, equal beam ulcrum,

draw pin pocket, and bumper and deck. This object. l attaininthe following manner,

reference being had to the accompanying drawings, in which:

saddle, having Vside surfaces 2-2 to which the cylinder structures are bolted. ln the saddle are formed pasageways 3-3- through which high pressure steam passes to the cylinders in the direction of the arrow, Fig. 2.- A single pasageway is divided into two pasageways leading, to the upper 'surface of the saddle, so that the necessary pipes leading tothe cylinders can becoupled theretov in any suitable manner.

At the `forward end of the structure is the bumper 4, and under the bumper are the vdraw'pin pockets 5. This portion of the structure is reinforced by ribs 6 and 7. 8 is the center pin bearingfand this Amay be ar ranged to receive a center pin, or the center pin may form a part of the structure, depending somewhat on the type of the loco- `motive to which the invention is applied.

low, so as to make it as'light as possible, while openings 9- 9 are formed in the structure for the purpose of'reducing its weight.

Extending from the saddle are four longii tudinal ribs 10 which add strengthV and ri- "gi'dity to the structure,and extending through l thecentre of the cylinder saddle is a strengthf ening partition 11. which;V is perforated in l Y order to lighten theV sameand to-allow for '50 reaming operations, the openings in the struoi ofitheflocomotive are secured.

It will be -noticedthat the structureV is hollturejbeing such that, access may be had to the interior thereof.l v

At one end of the structure is a depending bracket 12,` which forms the bearing for a radius bar, and directly in `front of kthis bean 55 ing are two depending plates 13--13, which.'

form they bearing for the equalizing beam, the

Vpivot pin for the said beam passing through openings 14;.

15 are brackets to which the Waist-sheets 6 0 In this end of the structurel are transverse partitions 16, shown by dotted lines in Fig. 1

and full lines in Fig. 6, and extending from the saddle structure to the bumpers are in- 6 5 ternal ribs or partitions 17. These latter partitions as well as the partitions 16 have Vopenings 18 at intervals. By this construcf Y tion, the structure is provided with reinforcing ribs at different points where additional V strength is desired.

The frame 'of the engine is carried through a portion of the saddle and ts against the surface 19, Fig. 5, making a neat it,fwhile horizontal keys vmay beV located between'the 7 5 projections on the rameand the cylinder saddle. f

This end iframe may be located at either end of the locomotive, depending upon the particular type of locomotive under construction.V S0

said saddle having surfaces at each side to which the cylinders are secured; and surfaces below the cylinder surfaces to which the side frames of the locomotive are secured. 5 13, A locomotive end fra-me made in a single n casting and having a centrally located cylinder saddle at one end thereof, said saddle having a live steam passage with two branches extending to the upper surface of the casting, 10 said structure having surfaces at each side to which the cylinder Structures 'are secured, the frame being oifset below said side surfaces andV having surfaces for attachment to the Y side frames of the locomotive; and a bumper 15 at lche opposite end of the end frame.
